Pressure and fluid statics

Pressure on Fluid◆


Pressure is defined as external force by a fluid per unit area.

Pressure=Force/Area. (P=F/A)✔️

Unit= N/m^2  or. Pascal (Pa)✔️

Pressure is Scaler quantity.

Pressure=force/area

Pressure=weight of fluid/area

Pressure=mg/A........ {Eq.1}

Density=mass/volume

Mass= density × volume

Mass= density × A × h...........{put in eq..1}

Pressure=density × A × h × g/A

Pressure= ρ× g × h ✔️

Unit= N/m^2 ✔️

◆Pascal's law◆


According to Pascal's law, the pressure intensity of fluid is same in all direction at  a given level.
